The energy required to control NO/sub x/ emissions from gas turbines, reciprocating engines, process heaters, and boilers is discussed. The energy cost for controlling NO/sub x/ is often viewed as the efficiency loss due to less than optimum combustion. However, this efficiency loss represents only a portion of the total differential energy cost. Considerable energy must be used to manufacture auxilary materials and equipment which are often needed to reduce NO/sub x/ emissions. The energy cost of NO/sub x/ control related to less than optimum combustion conditions is emphasized. In general, any combustion device becomes more efficient at the expense of increased NO/sub x/ production. The high temperatures that encourage NO/sub x/ formation are also conducive to higher heat transfer efficiencies.
